Associated PressEstonian natives Dmitri Svertskov, 36, and Roman Seminog, 24, have been convicted of raiding Chase ATMs at seven locations around the Island in the spring of 2012. Chase has covered its customers' losses, a law enforcement source said.

STATEN ISLAND, N.Y. -- Their first stop is an upstate prison.

Afterward, it's likely a one-way trip back home for two Eastern European men who siphoned more than $50,000 in customers' hard-earned cash from Chase ATMs around the borough.

Estonian natives Dmitri Svertskov, 37, and Roman Seminog, 24, were sentenced Tuesday to two to six years behind bars for using "skimming" devices to obtain customers' banking account information and personal identification numbers, said prosecutors.

Armed with that data, the duo illegally lifted money from seven locations around the Island in the spring of 2012, said prosecutors. Chase has covered its customers' losses, a law enforcement source said, adding that hundreds of accounts were compromised.

The thefts occurred between March 23 and April 23 of last year, and were uncovered by Chase, said a law enforcement source.

"Skimming" has been around for several years and is a favorite of Russian and Eastern European criminals, authorities say.

Skimming devices are attached to an ATM and grab information from the magnetic strips on the backs of ATM cards. A hidden camera gleans customers' PINs as they punch them into the ATM keyboard, said the source. The hijacked information is transferred to a blank card and used to withdraw cash.

In May, the defendants pleaded guilty in state Supreme Court, St. George, to felony counts of second-degree grand larceny and first-degree identity theft, said a spokesman for District Attorney Daniel Donovan. Those were the top counts against them.

Based on their criminal convictions, Svertskov and Seminog potentially face deportation to Estonia after serving their prison sentences, said authorities.
